I have a whole flock of HP cables labeled 12979-600xx. That sounds really
familiar to me, but I'm drawing a blank on what these cables are for. In
addition to the part number, they say "Extender Cable" on them. Based on the
box they were in, I suspect they have something to do with disc drives.
However, that part number doesn't show up in my 7906 manuals, I know the
7900 daisychain cable is 13212, and they aren't I/O chassis extender cables.
Anyone know offhand what these cables are for? They have one standard HP
edge card connector on each end.
Thanks!

My "HP 1000 Computers Hardware Data" book from 1978 has a listing for the
"12979B Dual-Port I/O Extender" for M/E/F-series computers. There are
several cables listed as part of this product:
12979-60024 I/O data cable
12979-60008 I/O control cable
12979-60025 power control cable
A later version of this book (1982) lists an additional cable number:
12979-60028 I/O data cable
In addition to the part number, they say
"Extender Cable" on them.
That seems to confirm the above.
...they aren't I/O chassis extender cables.
Ummm....
Thanks!
You're welcome.

familiar to me,
The 12979 PN sounds real familar to me too. I'm about 99.5% certain that
it's something for the HP 1000 computer. I THINK 12797 is the IO expansion
chassis. If so, this might be the cable that connects it to the main CPU
chassis.

Turns out it WAS for an I/O extender, 12979, which is the extender for the
21MX. I'm used to thinking of an extender as a 2155 (2100 version). My bad.
